Simpler Script
Authored by: signals on Dec 18, '02 03:31:07PM

I took your script and modified it a little to do less work. It no longer uses multiple calls to "echo" to display text, it uses a single call to "cat." Most of the variable assignments have been removed since many were only used once, and the AppleScript is cat'ed into osascript now instead of multiple "-e" arguments. There seemed to be no reason to assign the output of osascript to a variable and then echo it, so I removed that and I've redirected stderr to /dev/null so I don't get the

## Component Manager: attempting to find symbols in a component alias of type (regR/carP/x!bt)

message. And I also removed the "|| echo \"${item_parent}\"" from the 'determine absolute path' part, as it didn't seem necessary. I can't think of a way the OR could be executed and still have the script work. I also used "$0" in the usage display so you can call the script whatever you want without having to edit it so the usage: display says the right name.

Someone please fix anything I might have broken.

Here it is:

----Begin Script----


# Usage Display
if [ $# -eq 0 ]; then
cat <<EOF
Usage: ${0} alias
where alias is an alias file.
Returns the file path to the original file referenced by a
Mac OS X GUI alias. Use it to execute commands on the
referenced file. For example, if aliasd is an alias of
a directory, entering
% cd \`${0} alias\`
at the command line prompt would change the working directory
to the original directory.


# Main routine
# If it's a file and not a link, we continue
if [ -f "$1" -a ! -L "$1" ]; then
# Find the absolute path to the file
item_parent=`dirname "$1"`
item_path="`cd "${item_parent}" 2>/dev/null && pwd`/`basename "$1"`"

# Run the AppleScript to decode the alias.
cat <<EOF | osascript 2>/dev/null
tell application "Finder"
set theItem to (POSIX file "${item_path}") as alias
if the kind of theItem is "alias" then
get the posix path of (original item of theItem as text)
end if
end tell

----End Script----

Oops, sorry... I lost the indenting when I pasted the script into the web browser. It should still work fine, it just looks funny.
